Plague of Plagues

From the Plague of Plagues: the sinfulness of sin, by Ralph Venning,

Sin has made men worship either (1) a false God, which is idolatry; or (2) God falsely, which is superstition...

(1) Idolatry is man's folly. To worship no God, or that which is not a God, but an idol, is folly...

(2) Superstition is man's folly, also, as to religion. This is the younger brother to idolatry; it is of the same womb with idolatry. Superstition is not worshipping a false God, but worshipping the true God falsely, in a way not commanded by God. It teaches and practises for doctrines the devices and commandments of men; that is to say, it worships, not according to the will of God, but to the will of man. This is called the sacrifice of fools (Ecclesiastes 5.1). They mind the matter more than the manner, and are taken up with the work done, though it is not well done. They mind the outside more than the inside, yes, and worship God more because they fear him, than because they love him.
